Thats a good point but I didn't see anything about pricing on the site and I read the whole thing. Also the 2.8 does NOT need a new hood and fits just fine. It doesnt appear that the 3.6 or 4.2 need a hood either but it does state that modifications are neccesary with 3.6 and 4.2

the GT500 crowd have the same issue, your options are really just, notch the hood framing, lower engine cradle/mounts, or buy a larger cowl hood

What I really like about this blower and Whipple, is that how these blowers maintain a steady blow till redline. If you look at the TQ curve, it's almost flat all the way to redline. Image you add a headers and blower Cam on this, the TQ would be solid flat.

The second most important thing (which I don't have an answer to), is which has the least "parasitic losses" which results a better final result. KB has always been famous for that. Whipple is very efficient too. But I don't have the facts among all these new PD blowers.

Thirdly, the throttle body and see how much bigger it is than the stock (even if you port the stock). This has a huge bottleneck on performance, if it's not large enough. In fact the new Mustange GT for 2011, has changed theirs to the shape and size of KB.

i know its a mustang magazine, but its the blower comparison im interested it, the TVS required 147hp to use where as the Kenne Bell only took 111hp

as for the hood and engine drop, Kenne Bell claims the 2.8 fits with no issue, its when you go for the bigger blowers the hood gets in the way. if it doesnt bother you, an aftermarket larger cowl hood would fix that problem.

Thanks for the info Liquid; Ya, KB has always been famous for their efficiency and cool air.

It's amazing how many vendors are building F/I for this car. And we are in the middle recession and high price gas time. Imagine people had more money to spend.

Not to hijack the thread, the new 2011 mustange engine is [technically] awesome too.

[UPDATE]Some info from the magazine:
"While it doesn't compare to the 500 hp required to drive a Top Fuel Roots blower, some of these larger street/strip superchargers required as much as 150 hp to spin them at 18,000 rpm and 20-plus pounds of boost. Not surprisingly, results from the blower dyno correlate perfectly with the chassis dyno. Configured to produce 20 psi of boost (a level not attainable with the TVS on the 5.4), the TVS checked at 18,000 rpm, 340 degrees of discharge temperature, and a whopping 147 hp worth of parasitic drive losses.
This means it took 147 hp to drive the TVS supercharger at this speed and flow level. By comparison, the Kenne Bell required only 12,700 rpm to produce the same 20 psi. Running the same boost level, the discharge temperature registered only 282 degrees, and the Twin Screw blower absorbed only 111 hp in the process. Thus the Twin Screw reduced the inlet charge temp, blower speed, and parasitic losses required to reach the desired boost level."

compression causes heat, which in turn does 2 things: 1. heats up the air which everyone knows colder air results in more power, and 2. the back section of the screws (where the air exits the blower) is the hottest and the screws themselves increase in size, and bang into each other resulting in metal shaving entering the engine

"Just how hot is hot? At crazy high boost 100-degree incoming air becomes 350-degree outlet air-that's a huge heat gain for a twin-screw blower. Jim says he horsebacks a 10-degree gain per pound of boost. Thus, when boost arcs into the 25-pound stratosphere, the hot blower rotors have expanded enough to crash into each other, destroying themselves and sending gritty metal bits downstream into the engine. The rotors always touch first at the gear end (discharge end) of the blower because it is considerably hotter than the inlet end, which you can think of as air-cooled."
-again from the same mustang magazine, http://www.mustang50magazine.com/tec...ger/index.html

the last part really isnt an issue unless your running high amounts of boost

i believe theres still the air to water intercooler under the blower with the heat exchanger mounted behind the radiator, and that the liquid cooling uses the water from the heat exchanger. i think its more of an over-kill thing, safety thing for expanding screws, lower the outlet temps before hitting the intercooler so it can get even colder air charge temps

"...What IS true: We anticipated that this would happen - we are never finished - and yes, Ford DOES deserve to win now and then. To think that GM can come out with a car to make ford throw in the towel is simply foolhardy..." - fbodfather

The KB blower looks good and efficient but I believe you will get more power out of a bigger blower. I am not taking anything away from KB but it looks like they were the ones who did the test in the article and not a 3rd party. I think the tests will always be skewed towards a manufacturers product that is doing the test. I can't remember the comparison between the Hennessey 650 car and the 725 Super Snake - didn't they dyno close to the same?? It will be interesting to see these on the new camaros - can't wait.
